To all whom it may concern.-

Be it known that I, JOHN HALL, man ufacturer, of Hearthcote road, Swadlincote, in the county of Derby, England, have invented certain new and useful Improvements in Apparatus for Use in the Manufacture of Bricks or the Like, of which the following is a specification.

This invention has for its object to provide improved, apparatus whereby the bricks can be separated or spaced apart mechanically and in quantities at one time.

According to my invention I provide atable having a top of approximately the same length and width as the biggest batch of bricks delivered by the machine at one delivery and divided along its length into sections equal in number to the number of bricks in the said batch. I make the said sections movable in the direction of the length of the table, and I provide suitable mechanism, including a series of levers each connected to'one of said sections and a means for moving said levers, whereby the said sections can be moved together or closed up simultaneously, so as to form a solid or continuous table-top, and whereby also the sections can be moved apart or opened out simultaneously, so as to separate the bricks to any desired extent.

The accompanying drawings illustrate a modification of apparatus com prising a tabletop in which the movable sections are divided into two groups adapted to open out in opposite directions from a fixed central section, Figure 1 being a side elevation; Fig. 2, a plan; Fig. 3, an end elevation looking in the direction of the arrow a in Fig. 1, and Fig. 4: a vertical cross-section on the line A B of Fig. 1 looking in the direction of the arrow 6.

The framing of the apparatus consists of a pair of uprights 1 1*, connected, respectively, to a similar pair of uprights 2 2 bya pair of longitudinal supports 3 3.

4 4? are two parallel horizontal guide-bars connected to and carried by the uprights of the framing. They are formed with shoulders 5, which serve as abutments for the uprights.

6 represents the movable table-top sections. They may be provided in any suitable number. In the present embodiment of the invention nine movable sections are shown arranged in two groups of four and five, situated, respectively, on the right hand and left hand of a fixed table-top section 7. Each movable table-top section consists of a casting comprising two vertical side parts 6 6 connected together by an upper horizontal flat part 6 and each terminating in a lower flat foot 6. The said side parts are bulged and perforated longitudinally to receive the guide-bars44, whereby the movable sections are strung on the said guide-bars and can slide to and fro along the latter within the limits of the shoulders 5. The section 7 is of similar construction to the movable sections, and it is strung on the guide-bars 4 4 in the same manner; but it is fixed in its place 'thereon by means of a set-screw 8.

9 9 are a pair of arms for each movable sec tion, formed with bent portions 9 9*,whereby the arms 9 are fixed to the undersides of the feet 6 of such sections. The arms 9 9 of each movable section carry a cross-pin 10, with which engages the upper arm 11 ofa lever 11 12, fixed on a cross-pin l3,pivoting in brackets 14:, fixed on the supports 3 3. All the levers 11 12 belonging to one group of movable table-top sections 6 are parallel to one another in the vertical plane and at an opposite inclination to the levers of the other group. The length of the upper arms 11 of the levers ll 12 varies and increases in direct proportion to the distance of the respective pivot-pins 13 from a vertical center line drawn through the center of the fixed tabletop section 7. Consequently the arms 9 are made of varying length and extend upward or downward, as the case may be, in order to bring their cross-pins 10 to meet their corresponding upper arms 11. The arms 12 of the lovers of the right-hand group are pivoted at their lower ends to a common connecting-rod l5, and the arms 12 of the levers of the left-hand group are pivoted to a common connecting-rod 1o.

17 is the upper arm, and 1Sis the lower arm, of a lever 17 18, mounted on a transverse pin 19, pivoting in brackets 20, fixed to the supports 3 3. r

21 is a connecting-rod connecting the outer end pin 22 of the connecting-rod 16 with the upper arm 17 of the lever 17 18. The lower arm 18 of this lever is pivoted to the inner end 23 of the connecting-rod 15.

24 is an operating-lever handle mounted on a pivot-pin 25, carried in brackets 26, fixed to the uprights 1 1*. The connecting-rod is pivoted to the lower end 2'7 of the operating-lever 24.

Fig. 1 shows the apparatus with the tabletop opened outthat is to say, with the-movable table-top sections 6 moved away from the fixed table-top section 7.

Referring to Fig. 1, the operation of this modification of the improved apparatus is as follows: When intended for use with a brickmaking machine of the ordinary type, this apparatus or table is arranged with its length parallel to the length of the batch of bricks as delivered by the'machine and with the movable table-top sections 6 closed up .together toward the fixed table-top section 7 by pushingin the lever 24: in the direction of the arrow at, so that each brick of the batch will be delivered onto a separate section of the table-top, as indicated in dash-dotted lines at 28 in the figures. When the whole of the batch has been delivered onto the table-top, the tabletop is opened out by operating the lever 24 in the direction opposite to that of thearrow a, so as to move the sections away from the fixedsection 7 and apart from one another to the distance which it is desired shall be provided between the bricks for drying purposes. As each section of the opened-out table-top carries one brick of the batchfthe whole of the bricks of the batch will now have become separated or moved apart simultaneously to the distance required for drying, as above stated. While the table is thus extended the separated bricks are pushedonto a pallet and carried in their-separated format-ion to the drying-shed or drying-ground and the table is closed up again, ready to receive a fresh batch of bricks from the machine.

The sections composing the table-top and the mechanism for operating the same may be constructed and arranged in various ways.

When it is desired that the whole of the movable sections shall open out in one and the same direction from a fixed point or fixed section at one end of the table-top, the whole of the mechanism is arranged as in the case of one or other of the groups of sections of the arrangement above described, according to the direction in which the table is to open and according to the position of the operatinglever at one or the other end of the table.

Instead of having recesses the sections may be provided with trunnions, with which the levers may engage.

The table-top may also be constructed and operated on the principle of lazy-tongs.

What I claim, and desire to secure by Letters Patent, is

1. In apparatus for separating bricks and the like articles the combination of a series of movable table-top sections, a means for guiding said sections toward and from each other, a series of pivoted levers each engag ing at its upper end with one of the said sections, a connecting-rod connecting together the lower ends of the said levers, and an operating-lever connected to said connectingrod, whereby said sections can be moved simult-aneously toward each other to receive the articles, and away from each other to separate the articles.

2. In apparatus for separating bricks and the like articles the combination of a series of movable table-top sections, a fixed tabletop section, longitudinal supports along which the movable sections can slide toward and also away from said fixed section, a series of parallel pivoted levers each engaging at its upper end with one of the-said movablesections, 2. connecting-rod connecting together the lower ends of the said .levers, and an operating-lever connected to Said connectingrod, whereby said movable sectionscan he slid simultaneously toward said fixed.section to receive the articles and also whereby said movable sections can be slid away from said fixed section to separate the.articles, substantially asset forth.

3. In apparatus fonseparating bricks .and the like articles, .the combination of a fixed table-top section,agr011p of movabletabletop sectionssituated onone sideof the fixed section, agrou p of movabletable-top sections situated on the'opposite side ofsaid fixed section, longitudinal supportson whichsaid fixed section is fixed and along-which said movable sections can slide toward and alsoaway from said fixed section, a seriesof parallel pivoted levers engagingat their upperends severally with thesections of onegroup of :movablesections, a ,connectingn'od connecting together the lower ends of the said levers, ,a series of parallel pivoted levers engaging at .their upper ends severally withthesections of the othergroup of movable sections, a connect ing-rod connecting together thelower ends of the last-mentioned levers, a pivoted lever, a connecting-rod connecting the upperwend of this said pivoted lever with ,the first-mentioned connecting-rod, a connection connecting the lower end of thesaid pivoted lever with the second-mentioned connecting-rod,

andan operating-lever connected to this con- .necting-rod, whereby the movable .sections of both groups can be moved toward the fixed section to form an approximately continuous table to receive the articles and alsowhereby they can be moved .awayfrom thesaid fixed section to separate the articles substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
